Team suggests a way to protect autonomous grids from potentially crippling GPS spoofing attacks

Posted by in categories: biotech/medical, cybercrime/malcode, drones, engineering, internet, robotics/AI

Not long ago, getting a virus was about the worst thing computer users could expect in terms of system vulnerability. But in our current age of hyper-connectedness and the emerging Internet of Things, that’s no longer the case. With connectivity, a new principle has emerged, one of universal concern to those who work in the area of systems control, like João Hespanha, a professor in the departments of Electrical and Computer Engineering, and Mechanical Engineering at UC Santa Barbara. That law says, essentially, that the more complex and connected a system is, the more susceptible it is to disruptive cyber-attacks.

“It is about something much different than your regular computer virus,” Hespanha said. “It is more about cyber physical systems—systems in which computers are connected to physical elements. That could be robots, drones, smart appliances, or infrastructure systems such as those used to distribute energy and water.”

In a paper titled “Distributed Estimation of Power System Oscillation Modes under Attacks on GPS Clocks,” published this month in the journal IEEE Transactions on Instrumentation and Measurement, Hespanha and co-author Yongqiang Wang (a former UCSB postdoctoral research and now a faculty member at Clemson University) suggest a new method for protecting the increasingly complex and connected power grid from attack.

The Freedom of Life Extension

Posted by in categories: biotech/medical, life extension

Life extension would allow everyone to enjoy a higher degree of freedom.


Freedom is a rather big deal in this age. We want freedom of speech, political freedom, press freedom, religious freedom, and freedom of choice over anything that may concern us directly. Different kinds of freedom are available in different amounts in different areas of the world, and while many people tend to see the glass half empty and complain that freedom is not equally distributed everywhere, it’s undeniable that we enjoy far greater liberty than previous generations. It’s not always easy to act upon your choices, and sometimes you’re free to choose in theory but not in practice, but overall, we enjoy options that who came before us couldn’t even dream of.

Take health, for example. Two hundred years back, if you didn’t want to get the flu, or any other infectious disease, you didn’t have the option not to do so. The mechanism through which infectious diseases manifest and spread wasn’t even remotely understood, so you didn’t have any idea what you should or shouldn’t do to minimize your risk of falling ill; basic hygiene wasn’t exactly a standard, and drugs and vaccines were nowhere in sight. If you actively wanted to do something to prevent getting the flu—which, at the time, might have killed you—you simply didn’t have this option.

Fitter Happier: Mattheiu Gafsou Investigates Transhumanism in New Book and Exhibition

Posted by in categories: biotech/medical, education, transhumanism

Transhumanists aim to do just that: to transcend the limits of the human body through the use of technology. Swiss photographer Matthieu Gafsou’s new book, H+ (Kehrer Verlag), documents Transhumanism through portraiture, still lifes and documentary photographs of Tranhumanist people, facilities, tools and technology. In photographing surgical procedures, laboratories, conferences and the like, Gafsou employed a hard flash to add a “clinical aspect” to his pictures. “This was important to me because I think [Transhumanism] is quite cold and [it] is about, not necessarily killing death but working on living longer,” he tells PDN. “But we are forgetting the body, we are forgetting the flesh, we are forgetting desire.”


In “H+,” Gafsou uses the visual language of science and technology to explore Transhumanism, the belief that the human body needs to be enhanced, perhaps even overcome.

Mechanism Behind Drug Resistance in Some Cancers Clarified

Posted by in category: biotech/medical

Researchers have figured out details about how some specific type of cancers become drug-resistant.


Researchers at the Rockefeller University have clarified the mechanism by which certain types of breast cancer become immune to specific drugs designed to eliminate them. More specifically, they figured out how the loss of the protein 53BP1 due to BRCA1 mutation allows cancers to become insensitive to PARP inhibitors [1].

Glowing bacteria on deep-sea fish shed light on evolution, ‘third type’ of symbiosis

Posted by in categories: biotech/medical, evolution

You may recognize the anglerfish from its dramatic appearance in the hit animated film Finding Nemo, as it was very nearly the demise of clownfish Marlin and blue-tang fish Dory. It lives most of its life in total darkness more than 1,000 meters below the ocean surface. Female anglerfish sport a glowing lure on top of their foreheads, basically a pole with a light bulb on its end, where bioluminescent bacteria live. The light-emitting lure attracts both prey and potential mates to the fish.

Despite its recent fame, little is known about anglerfish and their symbiotic relationship with these brilliant , because the fish are difficult to acquire and study.

For the first time, scientists have sequenced and analyzed the genomes of bacteria that live in anglerfish bulbs. The bacteria were taken from fish specimens collected in the Gulf of Mexico.

Not classing aging as a disease is not a major problem

Posted by in categories: biotech/medical, life extension

A common concern in the community is that the FDA, the EMA, and other bodies, such as WHO, do not classify aging as a disease and that this poses a problem for developing therapies that target aging. However, this is not really as serious an issue as some people would suggest; today, we will have a look at why that is.

Why this will not stop progress

Aging is a variety of distinct processes, damages, and errors; therefore, simply treating aging in clinical terms is not a viable endpoint. For a clinical trial to be conducted, it requires a verifiable indication, and aging is too general for the FDA and EMA to classify it as a disease.

Mid-week Cancer Study and Emergency Drill Fill Station Schedule

Posted by in categories: biotech/medical, health, space

Cancer and rodent studies were on the crew’s timeline today to help doctors and scientists improve the health of humans in space and on Earth. The crew also conducted an emergency drill aboard the International Space Station.

Flight Engineer Serena Auñón-Chancellor examined endothelial cells through a microscope for the AngieX Cancer Therapy study. The new cancer research seeks to test a safer, more effective treatment that targets tumor cells and blood vessels. Commander Drew Feustel partnered with astronaut Alexander Gerst and checked on mice being observed for the Rodent Research-7 (RR-7) experiment. RR-7 is exploring how microgravity impacts microbes living inside organisms.

Astronaut Ricky Arnold and Gerst collected and stowed their blood samples for a pair of ongoing human research studies. Arnold went on to work a series of student investigations dubbed NanoRacks Module-9 exploring a variety of topics including botany, biology and physics.
